First time I have posted anything here, hope its the right spot. I have an 88 IROC TPI, getting to the issue it starts sometimes then runs good, I've narrowed it down to no fuel at initial start-up, new fuel pump and filter putting out good pressure, will start every-time if you pull MAF grommet and spray with starter fluid, question is what relay or module controls the initial start-up? Car runs great once this is done and the start-up is intermittent as it will start once in a while, not too trustworthy right now! Thanks for any help.

 

you could have a issue with the ninth injector or cold start switch.

 

Thank you for the heads up, I will attempt it this weekend, it has to be something and I was at a loss as to where to start, want to see if its worth repairing or just switch over to intake and carb with no ecm.....

 

Im new to this site so bare with me. I used to have this hard start problem with my 91 5.7 tpi. After replacing almost the whole ignition and fuel system it turned out to be the ignition coil connectors. I took a pic of them and Im trying to figure out how to get them posted on here. I replaced them and the car fires off easy now.
